Abstract

See full text

Provided are a communication system and a communication protocol for logically connecting a source node and one or more destination nodes, and for controlling data communication between the individual nodes by employing a connection ID that is used to identity the logical connection relationship. Further, provided are a communication system and a communication protocol for correlating a connection ID with an offset address that designates in common the memory spaces included in one or more destination nodes, and for simplifying the designation of the offset address and the identification of the connection ID for data that are received. Furthermore, provided are a communication system and a communication protocol for inhibiting an increase in a delay time that occurs before data communication is initiated between a source node and a plurality of destination nodes.
